Bayonet LED Boat Lighting

The tungsten bayonet is commonly used in ceiling lights, spot lights and reading lights and is easily replaced with an LED alternative.

In order to identify the most suitable replacement for the bayonet lamp it is necessary to find the diameter of the metal cap and count the number of metal ‘spots’ located on the base. The most common diameter is a 15mm cap, although standard household 22mm versions are sometimes used as well as Edison Screw caps. If the cap has a 15mm diameter and one metal spot is located on the bottom, the lamp is a Ba15s or SCC version, if two spots are located on the bottom, the lamp is a Ba15d or SBC version. Occasionally the 15mm cap can have two metal spots and off set pins, in which case you require the Bay15d cap. Edison Screw caps are commonly 14mm diameter (E14 or SES) or 27mm diameter (E27 or ES).

There are two styles of LED bayonet replacements, spotlights or towers. The spotlight types are used to provide light in one direction and are best used in reading lights and spotlights, where light is required in a single direction. The tower types provide light in all directions and are suitable to light up wall lights, ceiling lights and large light fittings.

Please note all of our bayonet LED lamps are voltage regulated (10-30V), voltage spike protected and are not polarity sensitive - i.e. the LED will light up whichever way the positive and negative power is applied so no rewiring is required.
